I already miss my ERT UDP. :bigcry: However that was the past, this is the future. For those that don't know, my car has been gone for the past two months for necessary CPO work. Right before Christmas I went to shut the car off, pulled out the key, and the car kept running. I then packed it up and towed it off to my dealer with a list of things that needed fixing before the CPO ran out, and went off on my vacation. When I got back from Florida (see the DTM feature), there was a message on my voicemail that the transmission was going to be replaced gratis under the CPO along with all of the things I had listed. However it seemed I needed a new clutch. Badly. :evil: Pretty burned. Enter the Active Autowerke clutch kit and LTW flywheel, which necessitated the removal of my European Racing Technologies double-belt underdrive pulley, something which had given me 45,000 miles of raw TQ and decent HP. Since the tranny was out, the labor for the install was nil, so I had to capitalize. While it was at the dealer, some other necessary services took place. New thermostat, Inspection II, and these little babies were swapped out for a fresh pair. Anyone want to guess what they are? Suffice to say I have a lot less shake in the tail now on a hard upshift. :lol: Now the absolute coolness of my dealer, Tulley BMW, comes in. About a week before my car was finally ready, I receive this PM from the tech who is working on my car, claiming to have removed the "clutch pussifier" (©) from the car. His explanation: Today, when surfing another forum and giving advice to a soon-to-be E39 owner, I saw this, which is the exact piece that was removed from my car, albeit on an E39. The picture is a link to the site itself (thanks Wagz! ): "Pussifier" indeed. The proper name for this is the Clutch Delay Valve. Impressions I only have about an hour worth of seat time, but a few differences make themselves immediately apparent. A noticeable amount of my instantaneous, snappy torque is gone with the ERT UDP. In fact, the power delivery is different enough to feel like a different car - the power is smooth, and constantly builds to redline. Before, it felt like the torque was overtaken by the building horsepower as it dropped off higher in the RPM range, but now the power is smooth, and constantly builds to redline. Gone are the hiccups, the flat spots, and a good amount of the other high-RPM power quirks my car was experiencing in its previously weakened condition. Let's talk about the Active Autowerke clutch kit and LTW flywheel. I cannot believe how much grip this thing has. I have to admit, I dropped the clutch at redline just to see what would happen and the tires instantly lit up for the second that I held the gear. When my OEM clutch was new, it just wouldn't do this. It would glaze before it would ever grab at that high an RPM! Believe me, I know, I watched a friend of mine do it to my car about two years ago after he begged me to let him drive it. The takeup is also different from stock, right off the floor instead of towards the end of the release, and upshifts are pure heaven. Clutch engagement is instant and immediate, instead of the slight softness of the system with the Pussifier©, and the AA kit handles my wuss-ass NA power with ease. That's about it for now. I need to go out for a cruise and form a few more lasting impressions. :evil: Thanks to Lou (BMC) for helping me put the parts needed together while I was on the cruise, Kevin and Kevin from Tulley, and the rest of the Tulley BMW techs for just being a group of cool guys. I should also thank Rob Levinson from UUC, who was ready to go out of his way to help me when I hit a potential snag.
